Pipes Chimney are (usually black pipes) seamless pipes made of steel designed to function in boiler installations and installations with high temperatures. Boiler smoke pipes and chimney pipes made from heat resistant carbon and low-alloy steel, which withstand high pressure and temperature load. Exhaust pipes are used for parts of the termal energy heating devices such as boilers, fireplaces, kitchen stoves, chimney connections. Additional elements of the exhaust pipes are single-wall liners and wall rosette. Special joint solutions like adjustable knee (multi-segment pipe with a wide range of adjustable angle with optional revision window) and elbow chimney pipe allow to join several straight pipes and expand the flue vent system.

chimney knee (chimney elbow knee pipe) are exhaust pipe elements (static, single element bended piece or multi-element adjustable angle knees) for the construction or expanding of flue gas outlet (chimeny exhaust system) from the boiler, stove, fireplace outlet to the chimney inlet. Multi-part elbow element can be set to create a straight flue pipe or be part of the chimney connection with a desired angle. Chimney Elbow allows you to expand installations where simple straight chimney connections are not sufficient or the required angle to the chimney inlet system must have a right angle. Elbow knees and angle knees pipes are made of durable heat-resistant carbon steel resistant to high temperature of the boiler or furnace and are protected by a black heat-resistant paint to protect it against corrosion. Elbow knees and angle knees pipes can also serve as straight pipe connection elements.
